To all whom it may concern: the body of the members 2 23 extend to a point Be it known that I, EDMOND VERSTRAETE, indicated at 12, Fig. IV. of the city of St. Louis, in the State of Mis- 13 represents the hub of arms 14, carrying souri, have invented a certain new and usethe wire-supports 15 of an electric-light or 5 ful Improvement in Poles for Electric Wires, other system.

The upper end of the pole made in halves 2 3, (see Fig. 1H,) each spindle 19 is provided with a non-circular 8o half having a flange 4 on each side, by which head 22, by which it maybe turned by removthe halves are secured together through ing the cap 16 and pin 21, and after it is means of bolts or rivets 5. turned the pin and cap would be reapplied. 6 represents a strip or diaphragm extend On the lower end of the spindle 19 is coiled ing across the post and held between the t-heinneren'd of the guy-wire23,thatsupports 85 flanges 4 by the rivets 5.

It will thus be seen that of the post, and which is composed of wood the guy-wire is insulated from the metallic or some other non-conductor of electricity. post, and that by adjusting the rod or spindle This plug is grooved,as shown at 9,Fig.VIII, 19 the wire may be tightened. Above the 5 to receive the inner edges of the narrow strips guy-wire 23 the post is provided with a block 10, preferably of metal, placed between the 30, preferably composed of some insulating flanges 4 above the diaphragm (5. (See Figs. material, and which is held to the flange upon IV and VIII.) The flanges 4 do not extend thepole by means of straps 31. To this block 50 above the pointindicated at 11, Fig. IV, but is secured the guard-wire 32, (see Fig. 1,) 1 JO which prevents electric and other wires from falling onto the trolleyqvire.

In Fig. X, I have shown a modification, where the insulator 8, instead of being a plug, is in the form of a sleeve and fits over the upper end of the pole, and the cap is provided with sockets 30 to receive wire-supportin g arms.

I claim as my invention- 1. A metallic pole having a plug 8 of nonconducting material, in combination with a shaft or spindle 19 for holding a wire, substantially as and for the purpose set forth.

2. A metallic pole having a plug 8, in combination with an adjustable shaft or spindle 19 for holding a wire, substantially as and for the purpose set forth.

3. A metallic pole having a plug 8 for receiving an adjustable shaft or spindle 19, adapted to hold a Wire, in combination with a pin passing through the plug and shaft or spindle, substantially as and for the purpose set forth.

4. A metallic pole having a slot 25, in com bination with a plug 23 and a rod or spindle fitted in the upper end of the post and to which a wire passing through the plug is secured, substantially as and for the purpose set forth.

5. A metallic pole having strips 10, a plug grooved to receive said strips and fitting in the upper end of the pole, a shaft or spindle fitting in the plug and adapted to holda wire, and means for uniting the spindle to the plug, substantially as set forth.

(5. In a metallic pole, the combination of a plug fitting in the end of the pole, a removable cap fitting on the plug, an adjustable spindle fitting in the plug and adapted to hold a wire, and means for holding the spindle, substantially as and for the purpose set forth.

7. In a metallic pole, the combination of the plug 8, arms having a hub fitting over the plug and notched to receive the flanges 0n the pole, a cap fitting on the plug, a spindle fitting in the plug and adapted to hold the wire, and means for holding the spindle, substantially as and for the purpose set forth.
